BOB-BIN-HOLDER.

Specification of Letters Patent.

Patented May 9, 1916.

Application filed July 3, 1914.' Serial No. 848,934.

To all whom it may concern 7 Be it known that I, GEORGE H. GOLDSMITH, ofOld Orchard, in the county of York and State of Maine, a Citizen of theUnited States, have invented a new and useful Improvement inBobbin-Holders, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The present invention relates to an improvement in bobbin holdersparticularly adapted for warp-wound bobbins.

Among the essential objects of the inven tion is to provide an improvedmeans for supporting the follow wires; to provide whereby the followwires may bear against the bobbin with increased friction as the bobbingrows lesser in diameter, and to provide also whereby variation may beobtained in the draw of the thread after leaving the bobbin held by theholder.

The invention can best be seen and understood by reference to thedrawings in which Figure l is a plan of the bobbin holder. Fig. 2 showsthe holder partly in side elevation and partly in longitudinal verticalsection. Fig. 3 is a section on the line 3-3 of Fig. 2, and Fig. 4 is aforward end elevation of the holder.

' Referring to the drawings: 1 represents a bracket attachable to a rod2 upon which the holder is mounted, attachment being secured in theusual manner. The bracket 1 is provided with forwardly and upwardlyproject- Secured to of the bracket is provided with aforwardlyprojecting portion or butt 6 having openings therein. Extendingthrough these openings to turn within the butt are rods 7 7. These rodsare substantially parallelly arranged and project forward from the buttto extend over the face of the bobbin plate. Secured to the rods 7, 7are the follow wires 8, 8-which swing over the face of the bobbin platein the usual manner as the rods carrying the same turn within the butt.The rods 7, 7 extend through the openings in the butt and each rod isheld against endwise displacement by means of a yoke 9 which straddlesthe butt to bear loosely against the forward and rear ends thereof andwhich yoke is, se-

cured to the rod. In other words, each yoke is provided withinwardly-turned ends or flanges 10, 10 having a loose bearing,respectively, against the forward and rear ends of the butt. The'rodsextend through these turned ends of the yokes and the yokes are securedto the rods by means of binding'screws 11 tapped through the rear endsof the respective yokes and bearing against the rods. 1

The yokes 9 are overweighted in the sense that they are provided withoverweighted sides 12 which lap respectively around the respective sidesof the butt (see Fig. 3). The overweighting of the sides of the yokeshas the effect of overweighting the rods 7, 7 to which the respectiveyokes are secured and which turn with the rods. Moreover, the lateraldisposition of the weighted sides 1.2 of the yokes with relation to therods is e such as to exert an influence to turn the follow wires carriedby the rods inwardly,

this influence being at a minimum when cation through adjustment of therods 7;

in other words, by simply loosening the binding screws 11 the rods 7 andfollow wires may be moved adjustably and their positions determined andafterward maintained by again tightening the set screws. By means of thelaterally-overweighted yokes the frictional bearing of the follow wiresagainst the bobbin is gradually increased as the bobbin lessens indiameter, thereby tending at all times to impart a proper frictionalretardation to the unwinding of the bobbin. In Fig. 4 the overweightedmembers are shown exerting substantially their maximum pressure againstthe sides of the cop, indicated in dotted lines, and from which itshould be understood the thread is nearly unwound, the

view being simply illustrative. A considerable variation in the degreeof frictional retardation is ell'ected simply by adjusting the positionof the overweighted sides of the yokes with relation to the rods. andsuch adjustment may be obtained by tirst loose! int the binding screws11 and after the adjustment is obtained again tightening said screws. Astill further adaptability of the structure resides in the fact that thethread as it is unwound may be led from beneath the side of the drawwires in the usual manner or be passed u wardly from the bobbin aroundeither of t e rods 7. That is, the structure is capable of a side drawor a center draw of the. thread, a center draw being preferable undersome circumstances. In this connection it is to be observed by referenceto Fig. 1 that the bobbin holder is m unted at an angle with relation tothe right line of the rod 2 which tends to give a cross traversev to thethread as it is bein unwound from the. bobbin, which is an advantage ina bobbin holder. and this etfect is obtained whether the. thread drawsfrom under one of the follow wires with a side draw or has a center drawover one or the other of the rods 7.
